Is it necessary to wear Invisalign aligners while sleeping?

25 January 2023

Invisalign Aligners

Invisalign is a cutting-edge orthodontic treatment that utilises clear plastic aligners to straighten teeth. These aligners are custom-crafted to fit the patient’s unique dental structure, and are replaced every few weeks as the teeth gradually shift into their desired position. The aligners are virtually invisible and comfortable to wear, making them a popular choice among adults and teens.

To achieve optimal results with Invisalign, it is essential to wear the aligners for a minimum of 20 hours a day. This includes while sleeping as the constant pressure of the aligners on the teeth during this time helps to move them into their desired position more efficiently. This is one of the reasons why Invisalign is considered to be one of the most effective teeth-straightening treatments available today.

Benefits of Wearing Invisalign While Sleeping

Appropriate tooth positioning and alignment

Wearing Invisalign aligners overnight allows for maximum treatment time, as the aligners continuously apply pressure to the teeth throughout the night. This extended treatment time results in more efficient and effective straightening of the teeth, as the aligners are able to work while the patient sleeps. It also helps to ensure that the teeth reach their desired position in the shortest amount of time possible.

Prevention of nighttime grinding

Wearing Invisalign aligners while sleeping can also protect the teeth from the damage caused by nighttime grinding, also known as bruxism. Wearing the aligners while sleeping can act as a barrier between the teeth, preventing them from coming into contact and reducing the risk of damage. Additionally, this can further improve the outcome of the treatment by protecting the teeth during the straightening process.

Comfort while sleeping

Invisalign aligners are designed to fit snugly over the teeth and are custom-made to fit each patient’s unique smile, making them comfortable to wear. They are also made from a smooth, clear material which is gentle on the gums and cheeks, making them even more comfortable to wear, even while sleeping. Additionally, many patients report that they quickly get used to wearing the aligners overnight and find them comfortable enough to sleep in.

Consequences of Not Wearing Invisalign While Sleeping

  • Delayed tooth shifting: If the aligners are not worn overnight, the teeth will not be given enough time to shift into the desired position. This can prolong the treatment time and delay the final results.
  • Prolonged treatment time: Not wearing the aligners overnight can also increase the overall length of treatment, as it will take longer for the teeth to reach the desired position.
  • Reduced effectiveness: Without the constant pressure of the aligners, the treatment may not be as effective, and the final results may not be as satisfactory.

How Long Should People Wear Invisalign

The duration of Invisalign treatment varies from person to person, but on average it takes about 12 months. However, the key factor to achieve the best results is consistency in wearing the aligners for the majority of the day, ideally for approximately 22 hours. It is important to note that not wearing the aligners for the recommended amount of time can lead to suboptimal results. The duration of treatment can be discussed with our orthodontist.

Maintenance and Care of Invisalign Aligners

Proper maintenance and care of Invisalign aligners is crucial to ensure the success of treatment and to maintain the health of teeth and gums. It is important to brush your teeth after every meal, snack, and sugary beverage to remove any food particles and prevent tooth decay.

It is also crucial to clean the aligners regularly to remove bacteria and plaque buildup. This can be done by gently brushing the aligners with a soft toothbrush and clear, mild soap and rinsing them thoroughly before placing them back in the mouth. When not in use, the aligners should be stored in their protective case to keep them clean and safe from damage. Your orthodontist will also provide instructions on how to properly care for your aligners.


Proper maintenance and care of the aligners, as well as visiting a licensed orthodontic specialist, is important for reaching the optimal results and the success of the treatment. Make sure to follow the instructions of our orthodontists, as we will monitor the progress and make any adjustments if necessary.
